2. Set the meter selector to the OHMS position. The
following readings must be observed:
MOD487
LIGHT Switch
A
OFF Open Open
LO-BEAM <1 ohm <1 ohm
HI-BEAM <1 ohm <1 ohm
TAILLIGHT
Voltage
 NOTE: Perform this test at the socket end of the
taillight-brake light harness (pigtail). The ignition
switch must be in the ON position and either HI-
BEAM or LO-BEAM selected on the light switch.
1. Set the meter selector to the DC Voltage position.
2. Connect the black tester lead to the black wire; then
connect the red tester lead to the white/red wire.
3. With the ignition key in the on position, the meter
must show battery voltage.

lights are illuminated, inspect the Lights fuse. If bat-
tery voltage is shown on the meter, replace the bulb.
BRAKE LIGHT
Voltage
 NOTE: Perform this test at the socket end of the
taillight-brake light harness (pigtail). The ignition
switch must be in the ON position.
1. Set the meter selector to the DC Voltage position.
2. Connect the red tester lead to the red/blue wire; then
connect the black tester lead to the black wire.
3. With the brake applied, the meter must show battery
voltage.
NOTE: If the meter shows no voltage, inspect the

10-amp lights fuse, brake light switch, wiring harness,
or connectors.
Power Distribution Module
(PDM)
 NOTE: The module and wiring harness are only
serviceable as assemblies.
If there is any type of electrical system failure, always
check the fuses first.
 NOTE: The fuses are located in two power distribu-
tion modules (PDM) under the hood.
1. Remove all fuses from the power distribution mod-
ules.
 NOTE: To remove a fuse, compress the locking tabs
on either side of the fuse case and lift up.
6411-493
CAUTION
Always replace a blown fuse with a fuse of the same
type and rating.
NOTE: Make sure the fuses are returned to their

proper position according to amperage. Refer to the
amperage listed under each fuse on the power distri-
bution module.
2. Set the meter selector to the DC Voltage position.
3. Connect the black tester lead to battery ground.
4. Using the red tester lead, contact each end of the fuse
holder connector terminals individually.
